  真(zhen)空甩帶爐(lu)的熱(re)處理過程是(shi)什么(me)

  真空甩帶爐是(shi)生產合(he)(he)金(jin)(jin)(永磁材料)的(de)專用(yong)設(she)備,是(shi)先進鑄(zhu)片工(gong)藝(yi)取代傳(chuan)動鑄(zhu)錠工(gong)藝(yi)的(de)理(li)想替代設(she)備。是(shi)利(li)用(yong)真空(kong)感應(ying)熔(rong)煉法,把(ba)坩堝封(feng)閉(bi)在(zai)真空(kong)室中,利(li)用(yong)電磁感應(ying)產生的(de)渦流作為熱源,在(zai)真空(kong)或惰性氣體狀態(tai)下把(ba)合(he)(he)金(jin)(jin)(或是(shi)導電材料)原料進行脫(tuo)氣、熔(rong)化處理(li),通過坩堝傾爐系統澆鑄(zhu),經過中間包在(zai)水冷輥上急速凝固后(hou)形成薄片,再在(zai)水冷盤上進行慢速降(jiang)(jiang)溫,在(zai)撥鑿的(de)攪拌(ban)下,把(ba)合(he)(he)金(jin)(jin)降(jiang)(jiang)到30℃左右,形成大不(bu)薄厚均勻的(de)合(he)(he)金(jin)(jin)薄片的(de)一種熔(rong)煉設(she)備。

真空甩帶爐的熱處理過程是什么

  熱(re)處(chu)理工(gong)藝(yi)一(yi)般包(bao)括:加熱(re)、保溫、冷(leng)卻三個(ge)過(guo)程(cheng),有時(shi)只有加熱(re)與冷(leng)卻兩個(ge)過(guo)程(cheng)。這些過(guo)程(cheng)都是真空甩帶爐熱(re)處(chu)理工(gong)藝(yi)的互相銜接,不可間斷。

  加熱(re)(re)(re)是熱(re)(re)(re)處(chu)理(li)中重要工序之(zhi)一,真(zhen)空甩帶(dai)爐對金屬熱(re)(re)(re)處(chu)理(li)的(de)(de)加熱(re)(re)(re)方(fang)法很多(duo),早期(qi)是采(cai)用(yong)木(mu)炭和煤作為熱(re)(re)(re)源,進而使用(yong)液體與(yu)氣體燃(ran)料。電(dian)加熱(re)(re)(re)易(yi)于控制,且無環境污染;利(li)用(yong)這些熱(re)(re)(re)源可(ke)以的(de)(de)直接(jie)加熱(re)(re)(re),也可(ke)以通過熔融的(de)(de)鹽或是金屬,以***浮動粒子進行間接(jie)加熱(re)(re)(re)。

  此外(wai),加(jia)(jia)(jia)熱溫(wen)度(du)是熱處(chu)理(li)(li)工(gong)藝(yi)的(de)(de)重要(yao)工(gong)藝(yi)參數之一(yi),選擇(ze)和控制加(jia)(jia)(jia)熱溫(wen)度(du)是保證(zheng)真空熔(rong)煉爐(lu)熱處(chu)理(li)(li)質量的(de)(de)主要(yao)問題(ti);加(jia)(jia)(jia)熱溫(wen)度(du)隨被處(chu)理(li)(li)的(de)(de)金屬材料和熱處(chu)理(li)(li)的(de)(de)目的(de)(de)不同而異,但一(yi)般都是加(jia)(jia)(jia)熱到相(xiang)變溫(wen)度(du)以(yi)上(shang),以(yi)獲得高溫(wen)組織。
